Option 4
Task 1. To perform the work, you need to select a group of four among ten people. How many ways can this be done?

Task 2. Produce two shots. Event A - hit the first shot, event B - hit the second shot. What is an AB event?

Task 3. There are four standard parts in a batch of six parts. Naudachu selected three parts. To compose the distribution law of a discrete random variable X - the number of standard parts among the selected.

Explanation: In task 3, in any of the variants you have chosen, write a solution and fill the distribution table with a random value. Sample table:

X 0 1 2 3 4
